Product Description

The KMP Front Uniball Kit is a high-performance replacement for the front thrust arm rubber bushings on BMW F8X M2, M3 and M4 models. Designed to reduce unwanted suspension movement, it provides a more direct connection between the chassis and front suspension for sharper steering response and improved control.

Factory rubber bushings are designed primarily for comfort, but over time they can allow excessive deflection, fatigue, cracking and failure. This movement can create a vague, disconnected steering feel, especially during hard braking, aggressive cornering or track use.

The KMP Front Uniball Kit replaces the standard rubber bushings with a more precise uniball solution, helping minimise deflection and improve steering behaviour, turn-in response and feedback through the chassis. The result is a front end that feels more immediate, predictable and confidence-inspiring.

Manufactured from high-grade anodised aluminium, the kit is built for demanding road and track use, offering increased durability and a longer service life compared with standard rubber bushings.
